Specification of Letters Patent.

Application filed Juno 1, 1905. Serial No- 263,239.

To all whom it Tina/g; concern.-

Be it lmown that I, STUART W. ORAMER, a citizen or the United States, residing at Charlotte, in the countyoi' Mecklenburg and State 1 5 of North Carolina, have invented certain new and useful improvements in Humiditying and Ventilating Apparatus; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertain's to make and use the same.

My invention relates to means for treating the air in a room or factory, and has for its object to provide an apparatus which shall keep the air in said room cbnstantly in circulation and supplied with any preferred amount of moisture; also, that it shall add fresh air from the outside, which, too, is tobe supplied with moisture, and at the same time incidentally therewith to cleanse, cool, and warm the air, as may be desired.

The invention consists in certain improvements in construction, which Will be disclosed in the following specification and claims.

In the accompanying drawings, which form part of this specification, Figure 1 represents a vertical longitudinal section with some of the parts shown in side elevation; Fig. 2, a horizontal lon itudinal section of the same; Fig. 3, a detai on an enlar ed scale, of the damper in the upper vertica member of the casing; and Pi 4, a vertical. section of one of the spray-hea s, on an enlarged scale. v

Reference bein had to the drawings and the designating characters thereon, the numeral 1 indicates the casing of the humidifier, which is supported by a frame 2, which is secured to the ceiling of the roof 3 by the screws 4. The casing is divided into an u per and lower part riveted together at 5. T e upper part extends through the roof 3 and terminates in a ventilator of the usual t e 6. intersecting the casing 1 at practical y ,5 right angles is a cylindrical casing 7, with branched outlets 8 on each end. Extending axially through the horizontal casing 7 is a shaft 9, independently su ported on hangers 10, attached to overhea timbers 11 in the usual manner. This shaft is revolved by a pulley 12, driven by a belt. (Not shown.) On the shaft are two tans, one a right-hand fan 14 and the other a left-hand fan 15.

At the bottom of the framework 2, supporting the casing 1, is a conical-shaped funnel-like bottom 16, terminating in a receptacle 17, in which ,water is maintained at a constant level 18 through the medium of a valve and connections 19 and a supply-pipe 20 to a tank (not shown) which is automatically kept filled by a float-feed of the usual type. The water-level in'the receptacle is shown by a gage-glass 21. Over the water in the receptacle is a gauze strainer 22 to keep any lint that may get in the apparatus from clogging up the water in the receptacle 17.

23 is a damper in the u per vertical member of the casing 1, w 'ch regulates the amount of inflow of air from the outside.

24 is a sleeve on the lower vertical member of the casing, which is raised and lowered and which regulates the amount of air admitted to the casing from the room. The intention is that when the damper 23 is wide open, admitting all the required air from the outside through the ventilator 6, the sleeve 24 at the bottom is closed, preventing any air from entering the casing from the room and when the sleeve. is raised to its full extent it admits all the air re uired for the a paratus from the room, the amper shuts 05 the inflow of air from the outside through the ventilator-fi, and in'intermediate positions the damper and the sleeve are correspondingly opened or closed, so that more or less air is let in at the top or the bottom of the casing, as may be re llll'd;

opens and closes the damper 23.

27 is a shaft or axle on which the damper is supported. On each end of this shaft 27 are 25 is a ban le attached to an arm 26, which small drums 28, on which a cord or chain 29 1 31 represents spray-heads, which take water i from the receptacle 17 by sucking up through the supply-pipe 32, terminating in a gauze bag-strainer 33-. The water is sucked up through the spray-head and converted into spray by air, steam, or other elastic fluid under pressure through the branch pipes 34 and the valve 35 and the air-service main 36, to wh1ch it issupplied and maintained at a constant and uniform pressure by l pressor of any of the usual we known types an air-com-.

provided with an automatic pressure-regulator.

The spray-head 31 (shown in detail in Fig.

4) is briefly described as follows: The spray- IIO divided spray or aqueous vapor.

tity of Water discharged by the spray-head is v body 41, and is met by the fluid under pressure issuing from the nozzle 44, commin ling in the outer end of the orifice 46 and delivering or discharging in the form of a minutely- The quanregulated by the adjustment of the cap 45,

and the supply of fluid, air under pressure, or steam is regulated by the valve 35, which fluid serves to raise the water, as already eX- plained, from the reservoir 17 below through the pipe 32 on the principle of. the operation of an ejector.

The spray-heads are adjusted by hand, and

' to afiord access thereto the casing is provided with a door.

(Not shown.)

37 is a steam-pipe having a branch 38 provided with a valve 39 and terminating in a contracted nozzle 40 within the casing. I

The operation of the apparatus may be briefly explained as follows: A current of air is constantly delivered through the branch outlets 8, on each end of the horizontal cylindrical-casing 7, by the right and left hand fans 14 and 15, revolved by the pulley 12 on the shaft 9. The amount of air flowing through the casing is intended to be practically uniform. The proportion of air from the outside is regulated by the position of the dam er 23, which admits air supplementary to t at admitted through the opening between the conical bottom 16 and the sliding sleeve 24. So far it is evident that the function of the apparatus islargely thatof ventimoderate amount of steamcan be turned in through the steam-jet 40 to temper the incoming air from the outside through the ventilator 6.

While the function of the apparatus is largely one of ventilating, it is rimarily that of air-moistening and air wasiiing or cleaning. This result is accomplished by the spray-from the spray-heads 31, which constantly maintain a dense cloud of spray within the casing 1, through which the air must pass, whether drawn from the outside through the ventilator 6 ,or from the room itself throu h the opening between the sleeve 24 and the ottom 16.

It is obvious that the spray-heads can be set so that the amount of spray can be regu-.

cameo lated, so that the air delivered by the fans 14 and 15 through the branched outlets 8 can 4 either be air simply saturated or it can be surcharged by a fine vapor which will qliiilickly evaporate and be taken u by the air 17 ough the -room into which it isorcibly projected. through this apparatus can be continuously and constantly'carried on, even through the process of air-moistening may be intermit tently carried on at the same time for the purpose of regulation. This is accom lished' by the sim le device for cutting off t 0 airsupply to t e s ray-heads, either automatic' ally or by han the shaft 9, with its fans 14 and 15, revolving continuously and um'nter ruptedly. I distinctly profpose finely dividing the water into a state 0 more or less 818's? 'tic vapor in the spray-heads, so that it will be more readily absorbed, su'ch construction providing for an apparatus of the maximum -apacity, as well as a maximum cleaning. effect. Furthermore, in my improved apparatus above described I provide means for regulating the amount of'outside air that is mixed in'the apparatus, it not being a matter of hit or miss, but of actual adjustment.

It is also evident that ventilation By my invention ventilation is mainw tainedcontinuously and uninterruptedly, whereas air-Inoistening is provided intermittently as the circumstances may require.
